摘要： A semiconductor device is disclosed that includes an insulation substrate, a metal wiring layer, a semiconductor element, a heat sink, and a stress relaxation member located between the insulation substrate and the heat sink. The heat sink has a plurality of partitioning walls that extend in one direction and are arranged at intervals. The stress relaxation member includes a stress absorbing portion formed by through holes extending through the entire thickness of the stress relaxation member. Each hole is formed such that its dimension along the longitudinal direction of the partitioning walls is greater than its dimension along the arranging direction of the partitioning walls.

摘要： A casing of a liquid-cooled-type cooling device has a peripheral wall including mutually facing right and left side walls. A cooling-liquid inlet is formed at one end of the right side wall, and a cooling-liquid outlet is formed at an end of the left side wall corresponding to the other end of the right side wall. A parallel-flow-channel section is provided within the casing to be located between the left and right side walls and between the cooling-liquid inlet and outlet and includes flow channels through which cooling liquid flows. Internal regions of the casing located upstream and downstream of the parallel-flow-channel section serve as inlet and outlet header sections, respectively. The cross-sectional area of the inlet header section reduces from the cooling-liquid inlet toward the left side wall. The outlet and inlet header sections are asymmetric in shape with respect to the width direction of the parallel-flow-channel section.

摘要： A liquid-cooled-type cooling device includes a casing having a cooling-liquid inlet and a cooling-liquid outlet, and an outflow pipe connected to the cooling-liquid outlet. The casing includes a cooling-liquid outflow portion, and the cooling-liquid outlet is formed in a top wall of the cooling-liquid outflow portion. The outflow pipe has a bottom wall parallel to a portion of the top wall of the cooling-liquid outflow portion where the cooling-liquid outlet is formed. The bottom wall has a through hole for communication with the cooling-liquid outlet. A guide portion is provided on a portion of an upper surface of a bottom wall of the cooling-liquid outflow portion, the portion corresponding to the cooling-liquid outlet, so as to change, toward an upward direction, the flow direction of cooling liquid flowing into the cooling-liquid outflow portion. Thus, a flow resistance which cooling liquid undergoes when flowing out of the casing can be reduced.
